My inventionrelates tomachines 'forcoatf y ing or icing biscuits, cakes, lor other;V articles With sugar,c`hocolate orother materials..`

My invention is concerned particularly with machines inV Whichcakes aref fedonto a dipping frame` which is "dippe'dto'" Abring the vlovver surfaceof thecakes intocontact with icing or coating material, andfrom Which i. dipping frame the coat'edjca'kesjare received 4by arms and deposited, coated side up, "ona conveyer. AIn *such machines *considerable coating oricing `material elingstothe lcakes :after the dippinglfraine ,is-"raised andthe "excess material vis nthrown and spattered aboutV on themachine and the'floor." Thev Yimportant object of my 'inventionfis to provide means for automatically scraping oft' 4the coated cakes arejengaged by; the `depositing mechanism.

On the accompanyingidrawings ZI Vhave shown a machine ofthe class referred to YWith 'my improved scraping mechanism ap- -fplied. 7On the drawing Y f' Figure lis a Vside elevation-of a machine, Fig. 2 is a plan view, Fig. 3 isv a'sectional-view on'plane'3--j3,

1 vThe supporting structure lfor the machine Vcomprises the skeleton side frames 10fa`nd11,

SecuredY betweenV `these-side frames atjthe: upper edge thereof is a dipping troughor 'tank 12 which contains coating Aoricing material 13. Adjacent" the endsofthetank 12 Vare the vertical guide lWays 114 and 15for`the `verticalslidefrods `16 and '17g Therupper A endsof'these Aslidero'ds have-'the inwardly sides ""20 and2'1; are" thestrips`l241 a11`d`52`5b Ween Whichextend the'transversegbars and;26. Extending upwardly j from 'these bars Y.are 'pairs of jpinsj27 and'm28 1suitably spaced transversely on the' bars andach pairssupporting afwire"29,` thfese vviresbeing alllin a common plane "for receiving" the cakes ci to scribed the ldippingframe receivesicales,on its Wires 29and is then".l loweredintofthetank 12 to dip the cakes into the.materialy 13 and after raising of theframe', thescraperbar 34 'is shiftedunderneath the jcakes tofsc'rape surplus coatingoricing material from the* cakes after the dipping `operation vand before surplus coating' material therefrom.

,Extending parallel With thedipping frame iwhen the 'dipping frame` is inl its upperposition. YAbove the grid frame 35 isafpiisher plate' 37 which is. guided in fittings ,38,- and 39, 'cakesres'ting on the gridframein7 front ofthe pusher plate being movedonto :the

The strips`24 and12'5 f' havefthe guide slots 3Q .and 31' respectively'for` receiving the lower edges of' L-shapedleind' pieces A32 and '33 respectivelyb'etween'Whose upper Jjen'dsextends' a scraping' bar34, the.` tQP-Sfllr- 1 face' ofthis bar being a shortdistance]be-Y "loW thewires 29. l As'vvillfbekpresntlyfdei to' the'` right thereof is4 a'grid orl comb 'frame 35 Which"i's" secured`to tlietops. of frame sideslOand 11, the supporting prongs, or

Above'the pusherfplate is a platform 40 for cakes to be'coated, an incline 41 leading from thejplatform to the "front end` of the "pusher plate so that cakesA Willkbeffed tothe prongsV or ,ribs `36 Ain frontof the "pusher plate." At its sides the pusherplatehas the extensions l42 and 43 for abutting against 1 the endpieces`32 and 33 respectivelyV which support the scraper-bar 34. Theseprojections push the scraper rod across ,thedipping frame s Vin advance of the cakes fed to the Iameby thevpusherlplate;

Describing novv the mechanism/:for remoi/'ing the dipped cakes from.the dipping' v gframe, a shaft 61fis vjournaled between the framesides 10 and 1.1 'andsupportsfat its ri0 'ends the upwardly extending `arms' 62 and 63 Vwhich at their upper endsljouriialtherod k64j This rod supportsa row; of bow shaped rngers 65 between the endsl of Aeach of which I isstrung a Wire 66, thewires' forming. a

` fi'rid yfor receiving. the iced cakes from the ippiiig frame, Ongthe-shaft44is alcam 67 which is engaged by a cam roller'68-on the" end of the arm 69. extending down j wardly from shaft 6l, asweightedarni 70 50` extendingjfrom'tm shaft tending to hold fthe'cam roller against the cam. When the Y 'shaft 6l`is rocked during engagement of the l camiroller-.with 'the cam the fingers 65 'are -shiftedfirst underneath the dipping frame f 555 aiidthen away therefrom. During inward travel of the lingers' their ends `encounter `the v scraping :bar 34 'wh-ieh'- was previously shifted toward the fingersV the pusher plate 37 whichcharged' cakes 'ontothe dipy 60 ping frame. This shifting of the scraper bar bythe fingers will' carry "the bar a short distance underneath and across the icedsurfaces ofthe cakes so Vthat any surplus icing s is scraped away,'as clea'rlyindifatedn Fisv-f A l"being returned to the tank.` v

I do'not, of course, desire to be limited Onsone endof thel rod 64 is secured a 1 .f lare preferably 'utilized for reciprocating the f n Y* 'dip ing frame andshifting the pusher plate:V i .iggfgJEurnaled-iinjtheg'franiesidesflQ and4 11 5 below the: dippingframe is a.shaft-.4 4. which gearV pinion 71"with which meshes a rack -y72jatthe end of a rod 73 extending upwardly. from the cam lever 74, thiscain'lever being-Pivoted to' the machinefraiiie at 75 and at an intermediate point mounting the camroller 76 which coperates with the cam 77 on shaft 44, the weight 78 on the lever holdingithe cam roller to the cam. The

shape of the ycams 67 and 77 and their timing with relation to the cam 46 is such that after the dipping frame hasbeendipped to coat cakes thereon, thengers 67 will be shifted underneath` thek cakes to first.V cause the scraper Y34 to scrape olf superfluous material, andthenY the fingers 'are swung upwardly sufficiently to. receive the cakes, and are .then drawn .bodily outwardlyuntil their ends clear the dipping frame, and then the rod 64 is rapidly rotated to'rsW-ing the fin- "gers' through practically 180 degrees to invert the cakes and to deposit thein,iced side up, on a conveyer belt 79.Y

v A The automatic scraper `mechanism vforms a very desirable and valuable attachment as Y by' itsuse surplus icing material is scraped l.from the .cakes and dropped into the tank VIAand is .consequently prevented -from dripping or splashing on the machine and in Vthe vicinity whenthe cakes are rapidly removed from the dipping frame tothe contveyer. Considerable saving also results in c oatingmaterial for the scraper mechanism permits .only :1.predetermined amount ofvmaterial to remain .on thev cakes, all surplus to the exact construction and arrangement :shown and described Yas modifications are no `doubt possible which would still come within the scope of the invention.

I claim as follows:

l. In a coating machine of the class described, the combination with a tank for coating material, of a verticallyi'eciprocable dipping frame, horizontally reeiprocable feeding mechanism. for` feeding cakes to said frame, horizontally reciprocable receiving Vmechanism for receiving `dipped cakes from said frame,l a scraper bar supback by the receiving mechanism to scrape superfluous coating material from'the cakes before they are received by the receiving mechanis 2. In a coating machine 'of vthe class described, the combinationl with a tank for coating material, of a vertically' reciprocable r dir )piiig framegliorizontally reciprocable feeding mechanism for feeding cakes to said frame, horlzontally reclprocable receiving said frame, transverse guidevvays on Said frame, blocks in said guidewvays, a scraper bar extending between and supported on said blocks to reciprocateL horizontally thereon below said dipped cakes, said bar being disconnected from said feeding mech- 10 anism and receiving mechanism but being Copies of'thi's patent may be obtained for in the path thereof to be shifted .toward the Y receiving mechanism by the feeding mecha-` mechanlsm for recelvlng dipped cakes from -r nism before a dipping operation and to be shifted back by the receiving mechanism' to scrape superfluous coating material from the cakes before they are received by the receiving mechanism. l g
